I've seen a lot of memorial jewelry, and I've never seen a piece quite like this one. It is Victorian, and I'm guessing 1860 or so. We have two hears entwined . One is black enamel (probably representing the dearly departed), and one is gold with natural pearls (representing tears). In the center, and joining the two hearts together, is an enamel band with the letter IMO (In Memory of) inscribed in gold. Then there is another teardrop, suspended from the gold heart. The back of the piece has a spot, where glass was once, and it would have contained a locked of the beloved's hair. I have had these repaired in London, and had new glass put in. If it were mine, and I wanted it to memorialize a loved one, I would have put a locket of that loved ones hair in, and have the glass replaced. In fact, if I don't sell it soon and I keep it, I will do just that. The piece does come with a chain which is gold filled, but the pendant itself is unmarked but tested 10 carat gold. The pendant, counting the lovely pearl encrusted bale, measures 1 and 7/8 inches North to South, and 3/4 of an inch East to West. It weighs, 6.55 grams. What an unusual piece of history! Note: There are no missing pearls in this piece. The one at the top appears to be missing in the photo, but it is just darker and a little more worn than the others.
